Billionaire George Soros must have a firm “my place, not yours” policy now that his current squeeze and the ex-lover who’s suing him for $50 million both live in the same Manhattan apartment building.

The wealthy octogenarian left it to the condo board and doorman to referee between Adriana Ferreyr, the 28-year-old former Brazilian soap star who claims Soros reneged on promises of a $1.9 million apartment, and Tamiko Bolton, 39, the woman to whom he gave it instead.

Things became so testy between the rival women at 30 E. 85th St. — when the scorned Ferreyr managed to rent another apartment there — that each accused the other of harassment, according to court papers.

It didn’t help that after five years together, including vacations hobnobbing in St. Barts, Ferreyr says Soros broke things off just days after signing the contract on the apartment of her dreams.

The passive-aggressive catfight between the sultry actress and the sexy licensed pharmacist escalated to the point that Bolton began “slandering her to the board of the building, the management company, doormen and lawyers,” Ferreyr charges in her lawsuit.

Bolton, who was identified as a partner in Soros Fund Management on the list of attendees at several events around the world, including a UN summit on climate change, could not be reached for comment.

But she never actually worked for Soros and was merely his guest on these jaunts, Soros spokesman Michael Vachon said.

“Tamiko Bolton is not and has never been an employee of SFM,” he said.

Sources say she is the octogenarian’s frequent “companion,” traveling with him to events and meetings in Europe.

Bolton still lives in Apartment 7C, the one Ferreyr says she chose after months of real-estate searching.

She learned of the betrayal only during a brief reconciliation, when Soros — who today turns 81 — admitted during pillow talk that he gave it to his new gal pal.

At that point, according to the lawsuit, the two argued, and when things escalated she claims Soros slapped her across the face and tried to bash her with a lamp.

Her account and all the allegations in the lawsuit are “a delusional work of fiction,” spokesman Vachon said, calling it “obviously an attempt to extract money from my client, who is known to be a very wealthy man.”

Soros was furious that Ferreyr — who is currently taking economics and philosophy classes at Columbia University — found a lease in the building and did everything he could to get her thrown out, she claims, including hiring private investigators to stalk her.
